title: Anisotropy barrier enhancement via ligand substitution in tetranuclear {Co(III)2Ln(III)2} single molecule magnets.
abstract: The replacement of coordinated acetylacetonate for nitrate around a Dy(III) ion results in the enhancement of the single molecule magnet properties of a {Co(III)2Dy(III)2} complex, resulting in a large thermal energy barrier and reduced quantum tunnelling at low temperatures. The analogous Tb(III) complex displays field induced SMM behaviour.
